Description

Technical Field

[0001] This disclosure relates to the field of petrochemical technology, and more specifically, to a muffler connection device and a muffler. Background Technology

[0002] Vent silencers used in petrochemical plants are typically installed at the highest point of the plant or structure near the equipment to avoid the influence of medium noise and temperature hazards. To resist dynamic loads such as wind loads and seismic loads and to ensure their own stability, silencers are usually installed in a fixed manner. The pipeline system to which they are connected needs to use natural compensation or compensator compensation to achieve the necessary flexibility of the pipeline system and ensure the safe operation of the pipeline system.

[0003] Typically, the vent pipe and the bottom inlet pipe of the silencer body are rigidly connected. Because the vent pipe will experience large temperature changes during use, it will cause strong thermal expansion and contraction, generating great thermal stress at the rigid connection, which may even lead to failure or damage to the pipeline system or equipment.

[0004] However, as petrochemical plants continue to grow in size, the diameter of venting pipelines is constantly increasing, and the size and weight of silencers are also increasing significantly. Since silencers are installed in a fixed manner, it is very difficult to achieve natural compensation and compensator compensation in the pipeline system connected to them. This requires a lot of space and will increase material costs and construction difficulty. Summary of the Invention

[0005] The purpose of this disclosure is to provide a muffler connection device and a muffler to solve the technical problems existing in the related art.

[0006] To achieve the above objectives, this disclosure provides a muffler connection device for connecting the vent pipe of a muffler body to a housing. The muffler connection device includes a housing, a lower fixing plate, a first elastic element, and a stop block. The housing is used to clamp the vent pipe and is spaced apart from it. The housing extends vertically and is fixedly connected to the housing of the muffler body. The lower fixing plate is fixedly connected to the inner wall below the housing and maintains a gap with the vent pipe. The first elastic element is tightly fitted between the vent pipe and the housing, and is positioned above the lower fixing plate. The first elastic element allows the vent pipe to move vertically. The stop block is positioned between the vent pipe and the housing and fits against the vent pipe. The stop block is positioned above the first elastic element and allows the vent pipe to tilt.

[0007] Optionally, the muffler connection device further includes a second elastic member, which is used to fit tightly between the vent connection pipe and the housing, and the second elastic member is disposed above the stop block, and the second elastic member allows the vent connection pipe to move in the vertical direction.

[0008] Optionally, the muffler connection device further includes a pressing structure, which is fixedly connected to the housing and used to compress the first elastic element and the second elastic element in the vertical direction, so that the first elastic element and the second elastic element are tightly fitted with the venting connection pipe, and the stop block can move in the vertical direction.

[0009] Optionally, the clamping structure includes an upper fixing plate, a clamping disc, a clamping sleeve, and fasteners. The upper fixing plate is fixedly connected to the upper edge of the housing. The clamping sleeve is disposed between the venting connection pipe and the housing and is used to maintain a gap with the venting connection pipe. The clamping sleeve extends in the vertical direction and its lower end presses against the top of the second elastic element. The clamping disc is connected to the upper fixing plate via the fasteners, and the lower surface of the clamping disc presses against the top of the upper end of the clamping sleeve and is used to maintain a gap with the venting connection pipe.

[0010] Optionally, the muffler connection device further includes a sealing ring, which is disposed between the vent connection pipe and the housing and is used to maintain a gap with the vent connection pipe. The sealing ring is disposed between the clamping sleeve and the second elastic element, and the sealing ring is movable in the vertical direction.

[0011] Optionally, the fastener includes a fastening bolt, a fastening nut, and an elastic preload plate. The fastening bolt passes through the upper fixing plate and the pressure plate in sequence and is connected to the fastening nut. The elastic preload plate is capable of elastic deformation in the vertical direction and is disposed between the fastening nut and the pressure plate.

[0012] Optionally, both the upper fixing plate and the clamping plate extend horizontally. The first surface of the upper fixing plate, which is positioned close to the venting connecting pipe in the horizontal direction, is coplanar with the inner wall of the housing. The clamping sleeve is capable of sliding in the vertical direction relative to the first surface and the inner wall of the housing.

[0013] Optionally, the stop includes a second surface in the horizontal direction for approaching the vent connection pipe, the second surface being configured as an arcuate surface for protruding toward the vent connection pipe.

[0014] This disclosure also provides a muffler, which includes a muffler body and a muffler connecting device, wherein the muffler body includes a venting connecting pipe and a housing.

[0015] Optionally, the housing includes a housing body and a base plate, the base plate extending horizontally and connected to the interior of the housing body, the base plate having a mounting hole for the vent connection pipe to pass through, and the outer surface of the housing of the muffler connection device being fixedly connected to the base plate.

[0016] In the above technical solution, because the first elastic element allows the venting connecting pipe to move vertically, the lower fixed plate is fixedly connected to the inner wall below the outer shell and is used to maintain a gap with the venting connecting pipe, and the stop block is used to be set between the venting connecting pipe and the outer shell and is used to fit against the venting connecting pipe, the venting connecting pipe can be allowed to move vertically. During the vertical movement of the venting connecting pipe, the first elastic element can tightly seal the box between the venting connecting pipe and the outer shell, thereby improving the sealing performance. In addition, the stop block can allow the venting connecting pipe to tilt and swing. When the venting connecting pipe swings, it can swing with the stop block as a fulcrum, satisfying the swaying condition of the venting connecting pipe and preventing the venting connecting pipe from failing to connect to the shell.

[0017] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" refer only to the upper and lower as defined in the illustrated direction of the muffler, and directional terms such as "horizontal direction" also refer to the horizontal direction as defined in the illustrated direction of the muffler; they do not constitute a limitation on the arrangement direction of the muffler connection device in the use state of this disclosure. Terms such as "first" and "second" are used only to distinguish one element from another and do not have any sequential or important significance.

[0024] Reference Figures 1 to 3 As shown, this disclosure provides a muffler connecting device 5, which is used to connect the venting connecting pipe 3 of the muffler body 1 to the housing 100. The muffler connecting device 5 includes a housing 51, a lower fixing plate 52, a first elastic member 53, and a stop block 54. The housing 51 is used to clamp the venting connecting pipe 3 and is spaced apart from the venting connecting pipe 3. The housing 51 extends in the vertical direction A and is fixedly connected to the housing 100 of the muffler body 1. The lower fixing plate 52 is fixedly connected to the lower part of the housing 51. The inner wall is used to leave a gap with the venting connection pipe 3; the first elastic member 53 is used to fit tightly between the venting connection pipe 3 and the outer shell 51, and the first elastic member 53 is disposed above the lower fixing plate 52, and the first elastic member 53 can allow the venting connection pipe 3 to move in the vertical direction A; the stop block 54 is used to be disposed between the venting connection pipe 3 and the outer shell 51 and is used to fit the venting connection pipe 3, the stop block 54 is disposed above the first elastic member 53, and the stop block 54 can be used to allow the venting connection pipe 3 to tilt.

[0025] In the above technical solution, since the first elastic element 53 allows the venting connecting pipe 3 to move in the vertical direction A, the lower fixing plate 52 is fixedly connected to the inner wall below the outer shell 51 and is used to maintain a gap with the venting connecting pipe 3, and the stop block 54 is used to be disposed between the venting connecting pipe 3 and the outer shell 51 and is used to fit against the venting connecting pipe 3, the venting connecting pipe 3 can be allowed to move in the vertical direction A. During the vertical movement of the venting connecting pipe 3 in the vertical direction A, the first elastic element 53 can fit tightly against the venting connecting pipe 3 and the outer shell 51, thereby improving the sealing performance. In addition, the stop block 54 can be used to allow the venting connecting pipe 3 to tilt and swing. When the venting connecting pipe 3 swings, the venting connecting pipe 3 can swing with the stop block 54 as a fulcrum, satisfying the working condition of the venting connecting pipe 3 shaking and avoiding the failure of the venting connecting pipe 3 to connect the shell 100.

[0026] In one implementation, reference Figure 1 and Figure 2As shown, the muffler connecting device 5 also includes a second elastic element 55. The second elastic element 55 is used to tightly fit between the vent connecting pipe 3 and the outer casing 51, and is disposed above the stop block 54. The second elastic element 55 allows the vent connecting pipe 3 to move in the vertical direction A. In this embodiment, by providing the second elastic element 55, the sealing of the vent connecting pipe 3 can be further improved. In addition, the first elastic element 53 and the second elastic element 55 are respectively disposed on the upper and lower sides of the stop block 54, which can improve the balance of the vent connecting pipe 3 when swinging. Furthermore, the first elastic element 53 and the second elastic element 55 can be made of graphite material, but this disclosure does not limit the specific materials of the first elastic element 53 and the second elastic element 55.

[0027] Optionally, the muffler connecting device 5 further includes a clamping structure, which is fixedly connected to the housing 51 and used to compress the first elastic element 53 and the second elastic element 55 in the vertical direction A, so that the first elastic element 53 and the second elastic element 55 are tightly fitted with the vent connecting pipe 3, and the stop block 54 can move in the vertical direction A. By providing this clamping structure, the first elastic element 53 and the second elastic element 55 can be kept in a compressed state, thereby enabling the first elastic element 53 and the second elastic element 55 to fit against the outer wall of the vent connecting pipe 3, improving the sealing performance. The clamping structure can be constructed in any suitable shape and structure, and this disclosure does not limit it.

[0028] Reference Figure 1 and Figure 2 As shown, the clamping structure includes an upper fixing plate 58, a clamping plate 59, a clamping sleeve 57, and a fastener 6. The upper fixing plate 58 is fixedly connected to the upper edge of the outer shell 51. The clamping sleeve 57 is used to be disposed between the venting connecting pipe 3 and the outer shell 51 and to leave a gap with the venting connecting pipe 3. The clamping sleeve 57 extends in the vertical direction A and its lower end presses against the top of the second elastic member 55. The clamping plate 59 is connected to the upper fixing plate 58 by the fastener 6, and the lower surface of the clamping plate 59 presses against the top of the upper end of the clamping sleeve 57 and leaves a gap with the venting connecting pipe 3.

[0029] In this embodiment, the clamping sleeve 57 is disposed between the venting connecting pipe 3 and the outer casing 51 and is used to maintain a gap with the venting connecting pipe 3. The lower surface of the clamping plate 59 abuts against the upper end of the clamping sleeve 57 and is used to maintain a gap with the venting connecting pipe 3, thereby ensuring that the venting connecting pipe 3 can move in the vertical direction. In addition, by adjusting the tightness of the fastener 6, the position of the clamping plate 59 relative to the fixed plate 58 in the vertical direction A is adjusted, thereby adjusting the deformation of the first elastic element 53 and the second elastic element 55. This clamping structure is simple in design and easy for operators to operate.

[0030] Optionally, refer to Figure 1and Figure 2 As shown, the muffler connection device 5 also includes a sealing ring 56. The sealing ring 56 is used to be disposed between the vent connection pipe 3 and the outer shell 51 and to leave a gap with the vent connection pipe 3. The sealing ring 56 is disposed between the clamping sleeve 57 and the second elastic member 55, and the sealing ring 56 can move in the up-down direction A.

[0031] In this embodiment, the sealing ring 56 is disposed between the venting connecting pipe 3 and the outer casing 51 and is used to maintain a gap with the venting connecting pipe 3 to facilitate the movement of the venting connecting pipe 3 in the vertical direction A. The sealing ring 56 is disposed between the clamping sleeve 57 and the second elastic member 55 to prevent the clamping sleeve 57 from directly pressing the second elastic member 55 and causing damage to the second elastic member 55.

[0032] In other implementations, refer to Figure 1 and Figure 2 As shown, fastener 6 includes a fastening bolt 61, a fastening nut 62, and an elastic preload plate 63.

The clamping sleeve 57 can slide relative to the first surface and the inner wall of the outer casing 51 in the vertical direction. This facilitates improved stability of the clamping sleeve 57 in the vertical direction A.

[0034] Optionally, the stop 54 includes a second surface in the horizontal direction B for approaching the venting connection pipe 3. The second surface is configured as an arcuate surface protruding toward the venting connection pipe 3, which facilitates the venting connection pipe 3 to swing by relying on the arcuate surface.
